Aluminum electrolytic capacitors are devices that store electrical energy and are widely used in virtually every sector of industry or consumer electronics. The EEE-HAJ152UAP is an aluminum electrolytic capacitor designed for myriad applications and operations. This article details the application field and working principles of the EEE-HAJ152UAP.

Introduction

Aluminum electrolytic capacitor technology has advanced significantly since its introduction in the 1920s. It is produced based on the electrochemical principle of ion conduction and is primarily divided into tantalum electrolytic capacitors and aluminum electrolytic capacitors due to the materials used. Aluminum electrolytic capacitors help improve the mechanical precision of the power supply, conduct electricity more smoothly and quietly, and because of their high energy density and high energy storage capabilities, are used frequently in consumer electronics and industry.

Application Field of the EEE-HAJ152UAP

The EEE-HAJ152UAP is an aluminum electrolytic capacitor specifically designed for applications that require a high energy density, high energy storage capability, and outstanding derating curves. It has a wide operating temperature range from -55°C to +105°C, making it suitable for a variety of applications in consumer electronics or industrial sectors. It also features high ripple current capability and good self-healing properties, making it a reliable and long-term solution for many power systems and applications that require high frequency and ripple current.

The EEE-HAJ152UAP capacitor is commonly used in power supplies and power amplifiers, as well as in electrical transformers and electronic switching systems. It is also used for high frequency, high power signal processors, signal filters, and signal distribution boards. Furthermore, it is well-suited for voltage stabilization, voltage adjustments, and filtering services in automotive, mobile communication, computer, and other portable electronics.

Working Principle of the EEE-HAJ152UAP

An aluminum electrolytic capacitor consists of two metallic electrodes, which are separated by a dielectric material. Electrons are drawn to the negative electrode, between the two electrolytic plates, to store energy. The positive electrode’s oxide layer prevents electrons from flowing back to the positive side, thus creating a voltage drop.

In the case of EEE-HAJ152UAP, an anode oxidation layer is deposited by electrochemical anodization of an aluminum foil to act as the dielectric. A liquid electrolyte is used to facilitate the anodization process and provide the electrical connection between the electrodes. This electrolyte is a plasticized colloidal suspension composed of an organic thickening agent, an organic solvent, and alkali salts.

Due to the chemical reaction in the aluminum foil, electric energy is stored. As the energy levels in the electrolyte increase, electric current flows through the anode oxidation film and the dielectric solvent layer, thus creating an insulated barrier for electric current, and allowing for electrical energy to be stored and discharged.

The electric resistance of this insulated barrier created by the anode oxidation layer and dielectric solvent layer depend on several external factors, such as the concentration of the electrolyte and the temperature of the environment. This in turn changes the capacitance of the device, providing a wide range of applications for the EEE-HAJ152UAP.

Conclusion

The EEE-HAJ152UAP is an advanced aluminum electrolytic capacitor capable of providing high energy density and high energy storage capacity while also featuring good derating curves and high ripple current. It is widely used in power supplies and power amplifiers, as well as in electrical transformers and electronic switching systems. It is an ideal solution for many high frequency, high power applications due to the anode oxidation layer and dielectric solvent layer, which create an insulated barrier and facilitate electrical energy storage.
